Description

本発明は、工作機械や産業機械等に潤滑等の目的でグリスやオイル等の流動性潤滑剤を供給する各種潤滑ポンプに取付けられる所謂使い捨てタイプの潤滑剤用カートリッジタンクに関する。   The present invention relates to a so-called disposable type cartridge tank for a lubricant that is attached to various lubrication pumps that supply a fluid lubricant such as grease or oil to a machine tool, an industrial machine or the like for the purpose of lubrication.

一般に、例えば、図１０に示すように、この種の潤滑剤用カートリッジタンクＴａが用いられる潤滑ポンプ１は、モータ２で駆動されるポンプ部３と、潤滑剤の注入口５が形成され雌ネジ４ａが形成された凹部４の底面６に突設された管状の給油口部７とを備え、給油口部７に着脱可能に取付けられる潤滑剤用カートリッジタンクＴａから供給される潤滑剤をポンプ部３で吐出させるようにしている。
従来、潤滑剤用カートリッジタンクＴａとしては、例えば、図１０に示すように、潤滑剤が封入される伸縮可能な樹脂製のジャバラ筒状に形成された容器本体１０を備え、この容器本体１０から突出し潤滑ポンプ１の凹部４に形成された雌ネジ４ａに螺合する雄ネジ２３が形成されるとともに給油口部７が挿入される開口２１を有した取付口部２０を備えている。この取付口部２０は、容器本体１０の軸線を軸心とする小径の円筒状に突出形成されており、潤滑ポンプ１の給油口部７に着脱可能に取付けられる（例えば、特開２００１−１７３８８７号公報参照）。 In general, for example, as shown in FIG. 10, a lubrication pump 1 in which this type of lubricant cartridge tank Ta is used has a pump portion 3 driven by a motor 2 and a lubricant inlet 5 formed with a female screw. And a tubular oil filler port 7 projecting from the bottom surface 6 of the recess 4 in which 4a is formed, and a pump for supplying lubricant supplied from a lubricant cartridge tank Ta that is detachably attached to the oil filler port 7 3 is discharged.
Conventionally, as the cartridge tank Ta for lubricant, for example, as shown in FIG. 10, a container main body 10 formed in an expandable and contractible resin bellows cylinder into which a lubricant is enclosed is provided. A male screw 23 is formed to be screwed into a female screw 4a formed in the recessed portion 4 of the protruding lubrication pump 1 and has an attachment port portion 20 having an opening 21 into which the oil filler port portion 7 is inserted. The attachment port portion 20 is formed in a small-diameter cylindrical shape with the axis of the container body 10 as an axis, and is detachably attached to the oil supply port portion 7 of the lubrication pump 1 (for example, JP-A-2001-173887). No. publication).

このような潤滑剤用カートリッジタンクＴａを潤滑ポンプ１に取付けるときは、取付口部２０の雄ネジ２３を潤滑ポンプ１の凹部４の雌ネジ４ａに螺合することにより行なわれる。詳しくは、潤滑剤用カートリッジタンクＴａは通常時は、取付口部２０の雄ネジ２３に螺合する雌ネジを有したキャップ（図示せず）が取付口部２０に取付けられているので、先ず、このキャップを取付口部２０から取外す。この状態で、容器本体１０を逆さにして取付口部２０を下側にし、取付口部２０を潤滑ポンプ１の凹部４に挿入し、容器本体１０を回して取付口部２０の雄ネジ２３を潤滑ポンプ１の凹部４の雌ネジ４ａに螺合する。また、潤滑剤用カートリッジタンクＴａの底部１１を押圧するコイルスプリング３１が内装されたケース３０でこの潤滑剤用カートリッジタンクＴａを覆うとともに、このケース３０を潤滑ポンプ１にビス等で固定する。
そして、潤滑ポンプ１の使用の際には、コイルスプリング３１で常時潤滑剤用カートリッジタンクＴａを押圧して潤滑剤が給油口部７から押し出されるようにし、潤滑剤がなくなったならば、新たな潤滑剤用カートリッジタンクＴａと交換するようにしている。 Such a lubricant cartridge tank Ta is attached to the lubrication pump 1 by screwing the male screw 23 of the attachment port 20 into the female screw 4 a of the recess 4 of the lubrication pump 1. Specifically, since the lubricant cartridge tank Ta is normally attached to the mounting opening 20 with a cap (not shown) having a female screw that is screwed into the male screw 23 of the mounting opening 20. The cap is removed from the mounting opening 20. In this state, the container body 10 is turned upside down so that the attachment port portion 20 faces downward, the attachment port portion 20 is inserted into the recess 4 of the lubrication pump 1, and the container body 10 is turned to turn the male screw 23 of the attachment port portion 20. Screwed into the female screw 4a of the recess 4 of the lubrication pump 1. Further, the lubricant cartridge tank Ta is covered with a case 30 in which a coil spring 31 that presses against the bottom 11 of the lubricant cartridge tank Ta is covered, and the case 30 is fixed to the lubrication pump 1 with screws or the like.
When the lubrication pump 1 is used, the lubricant cartridge tank Ta is constantly pressed by the coil spring 31 so that the lubricant is pushed out from the oil supply port 7. The lubricant cartridge tank Ta is exchanged.

しかしながら、この従来の潤滑剤用カートリッジタンクＴａにおいて、比較的粘度の高い通常の潤滑剤を封入したものにあっては、容器本体１０を逆さにして、取付口部２０を潤滑ポンプ１に取付ける際に、取付口部２０から潤滑剤が漏れることはないが、近年、粘度の低いやわらかい潤滑剤を封入するものがあり、このものでは、キャップを取外してから、容器本体１０を逆さにして取付口部２０の雄ネジ２３を潤滑ポンプ１の凹部４の雌ネジ４ａに螺合して取付けるまでの間に、重力によって潤滑剤が取付口部２０から漏れ出ることがあるという問題があった。   However, when the conventional lubricant cartridge tank Ta is filled with a normal lubricant having a relatively high viscosity, the container body 10 is inverted and the attachment port 20 is attached to the lubrication pump 1. However, in recent years, there is a type in which a low-viscosity soft lubricant is sealed, and in this case, after removing the cap, the container body 10 is turned upside down to attach the mounting port. There is a problem that the lubricant may leak from the mounting opening 20 due to gravity before the male screw 23 of the portion 20 is screwed onto the female screw 4a of the concave portion 4 of the lubricating pump 1 and attached.

本発明は、このような問題点に鑑みてなされたもので、粘度の低いやわらかい潤滑剤を封入しても潤滑ポンプへの装着の際に潤滑剤が漏れることを防止できる潤滑剤用カートリッジタンクを提供することを目的とする。   The present invention has been made in view of such problems, and a lubricant cartridge tank capable of preventing a lubricant from leaking when mounted on a lubrication pump even when a soft lubricant having a low viscosity is enclosed. The purpose is to provide.

このような目的を達成するため、本発明の潤滑剤用カートリッジタンクは、流動性潤滑剤の注入口が形成され雌ネジが形成された凹部の底面に突設された管状の給油口部を有した潤滑ポンプに着脱可能に取付けられて該潤滑ポンプに潤滑剤を供給する潤滑剤用カートリッジタンクであって、潤滑剤が封入される容器本体と、該容器本体から突出し上記雌ネジに螺合する雄ネジが形成されるとともに上記給油口部が挿入される開口を有した取付口部とを備えた潤滑剤用カートリッジタンクにおいて、上記取付口部の開口を覆う樹脂製の覆栓を備え、該覆栓に上記給油口部の開口への挿入時に該給油口部によって切断される薄肉の切断溝を形成した構成としている。   In order to achieve such an object, the cartridge cartridge for a lubricant according to the present invention has a tubular oil supply port portion protruding from the bottom surface of a recess in which a fluid lubricant injection port is formed and a female screw is formed. A lubricant cartridge tank that is detachably attached to the lubrication pump and supplies the lubricant to the lubrication pump, and a container main body in which the lubricant is sealed, and protrudes from the container main body and is screwed into the female screw. A lubricant cartridge tank having a male screw formed and an attachment port portion having an opening into which the oil supply port portion is inserted, and a resin cover plug covering the opening of the attachment port portion, A thin cut groove that is cut by the oil supply port portion when the cover plug is inserted into the opening of the oil supply port portion is formed.

これにより、潤滑剤用カートリッジタンクを潤滑ポンプに取付けるときは、潤滑剤用カートリッジタンクは通常時は、取付口部の雄ネジに螺合する雌ネジを有したキャップが取付口部に取付けられているので、先ず、このキャップを取付口部から取外す。この状態で、容器本体を逆さにして取付口部を下側にする。このとき、取付口部の開口は覆栓によって被覆されており、この覆栓が潤滑剤を受け止めるので、粘度の低いやわらかい潤滑剤を封入した場合でも、潤滑剤が取付口部から漏れることを防止できる。そして、取付口部を潤滑ポンプの凹部に挿入し、容器本体を回して取付口部の雄ネジを潤滑ポンプの凹部の雌ネジに螺合する。このとき、潤滑ポンプの給油口部によって覆栓の切断溝が切断され、給油口部が覆栓を突き破るようになるので、給油口部が取付口部の開口に挿入され、給油口部の注入口と容器本体内とが連通されるようになり、容器本体内に封入されている潤滑剤が取付口部を通過して流出し潤滑ポンプに供給されるようになる。即ち、容器本体内に封入されている潤滑剤は、キャップを取外してから容器本体を逆さにして取付口部の雄ネジを潤滑ポンプの凹部の雌ネジに螺合して取付けるまでの間は容器本体から漏れないが、潤滑剤用カートリッジタンクを潤滑ポンプに取付けた後は、容器本体から流出して潤滑ポンプに供給されるようになる。   Thus, when the lubricant cartridge tank is attached to the lubrication pump, the lubricant cartridge tank is normally fitted with a cap having a female screw threadedly engaged with the male screw of the attachment port portion. First, remove the cap from the mounting opening. In this state, the container body is turned upside down so that the mounting opening is on the lower side. At this time, the opening of the mounting port is covered with a cover plug, and the cover plug receives the lubricant, so even if a soft lubricant with low viscosity is sealed, the lubricant is prevented from leaking from the mount port. it can. Then, the attachment port portion is inserted into the concave portion of the lubrication pump, and the container body is rotated to screw the male screw of the attachment port portion into the female screw of the concave portion of the lubrication pump. At this time, the lubricating groove of the lubrication pump cuts the cutting groove of the cover plug so that the oil supply port breaks through the cover plug, so that the oil supply port is inserted into the opening of the mounting port, and The inlet and the inside of the container main body are communicated, and the lubricant sealed in the container main body flows out through the attachment opening and is supplied to the lubrication pump. That is, the lubricant sealed in the container body is the container from when the cap is removed until the container body is turned upside down and the male screw of the mounting opening is screwed into the female screw of the concave part of the lubrication pump. Although it does not leak from the main body, after the lubricant cartridge tank is attached to the lubrication pump, it flows out of the container main body and is supplied to the lubrication pump.

そして、必要に応じ、上記切断溝を、上記給油口部の口径よりも大きな径の円形状に形成される円周溝と、該円周溝の中心及び該円周溝間に亘って形成される複数の縦溝とを備えて構成している。これにより、円周溝及び縦溝で囲繞される複数の片部が形成され、取付口部を凹部に取付けた際、切断溝が切断されると、これらの片部が分離するようになるので、給油口部が取付口部の開口に容易に挿入されるようになる。また、複数の縦溝を円周溝の中心から円周溝間に亘って設けたので、この縦溝が切断されると、円周溝の中心が切断されることになり、そのため、給油口部の注入口を覆栓が塞ぐことを防止できるので、確実に潤滑剤を潤滑ポンプに供給できるようになる。   Then, if necessary, the cutting groove is formed between a circumferential groove formed in a circular shape having a diameter larger than the diameter of the oil filler port portion, and the center of the circumferential groove and between the circumferential grooves. And a plurality of vertical grooves. As a result, a plurality of pieces surrounded by the circumferential groove and the vertical groove are formed, and when the attachment opening is attached to the recess, when the cutting groove is cut, these pieces are separated. The oil supply port is easily inserted into the opening of the mounting port. In addition, since the plurality of vertical grooves are provided from the center of the circumferential groove to between the circumferential grooves, when the vertical groove is cut, the center of the circumferential groove is cut. Therefore, it is possible to prevent the cover plug from blocking the inlet of the part, so that the lubricant can be reliably supplied to the lubrication pump.

また、必要に応じ、上記切断溝が切断されたとき上記円周溝及び上記縦溝で囲繞される複数の片部を夫々支持するヒンジを、上記円周溝の外側に形成される外周部と上記片部との間に設けた構成としている。取付口部を凹部に取付けた際、給油口部によって円周溝及び縦溝が切断され、片部は潤滑剤用カートリッジタンクの容器本体内に入り込むようになる。このとき、片部はヒンジによって支持されているので、片部はヒンジを介して外周部に接続され、片部が覆栓から離脱させられて容器本体に封入されている潤滑剤内を遊動することを防止することができる。これにより、片部が潤滑剤内を遊動して給油口部の注入口を塞ぐことを防止できるので、確実に潤滑剤を潤滑ポンプに供給できるようになる。また、使用後の潤滑剤用カートリッジタンクを、新たな潤滑剤用カートリッジタンクと交換する際には、使用後の潤滑剤用カートリッジタンクを潤滑ポンプから取外すが、この際にも、片部はヒンジを介して外周部に接続されているので、片部が離脱することを防止することができる。   Further, if necessary, a hinge that supports each of the plurality of pieces surrounded by the circumferential groove and the longitudinal groove when the cutting groove is cut, and an outer peripheral portion formed outside the circumferential groove, It is set as the structure provided between the said one part. When the attachment port is attached to the recess, the circumferential groove and the vertical groove are cut by the oil supply port, and the one part enters the container body of the cartridge tank for lubricant. At this time, since the one part is supported by the hinge, the one part is connected to the outer peripheral part through the hinge, and the one part is detached from the cover plug and floats in the lubricant sealed in the container body. This can be prevented. Accordingly, it is possible to prevent the one part from floating in the lubricant and block the injection port of the oil supply port portion, so that the lubricant can be reliably supplied to the lubrication pump. Also, when replacing the used lubricant cartridge tank with a new lubricant cartridge tank, the used lubricant cartridge tank is removed from the lubrication pump. Since it is connected to the outer peripheral part via, it can prevent that one part detaches | leaves.

更に、本発明においては、上記覆栓の外周部の表面に上記凹部の底面に当接する円形の突条を設けた構成としている。これにより、取付口部を凹部に取付けた際、外周部の表面に設けられた円形の突条が、凹部の底面と当接し、外周部の表面と凹部の底面とは略線接触で密着するようになる。この場合、外周部の表面と凹部の底面とを面接触で密着させた場合と比較して、接触場所に掛かる圧力が大きくなり、そのため、シール性が良くなる。 In a further, in the present invention has a configuration in which a contact with circular ridges on the surface of the outer peripheral portion on the bottom surface of the recess portion of the Kutsugaesen. As a result, when the mounting opening is attached to the recess, the circular protrusion provided on the surface of the outer peripheral portion comes into contact with the bottom surface of the concave portion, and the surface of the outer peripheral portion and the bottom surface of the concave portion are brought into close contact with each other by substantially line contact. It becomes like this. In this case, compared with the case where the surface of the outer peripheral portion and the bottom surface of the concave portion are brought into close contact with each other, the pressure applied to the contact location is increased, and thus the sealing performance is improved.

更にまた、本発明においては、上記覆栓の外周部の裏面に上記取付口部の端面に当接するとともに上記外周部の表面の突条と同軸で同径の円形の突条を設けた構成としている。これにより、覆栓を取付口部に取付けた際、外周部の裏面に設けられた円形の突条が、取付口部の端面と当接し、外周部の裏面と取付口部の端面とは略線接触で密着するようになる。この場合、外周部の裏面と取付口部の端面とを面接触で密着させた場合と比較して、接触場所に掛かる圧力が大きくなり、そのため、シール性が良くなる。 Furthermore it was or, in the present invention, provided with circular ridges of the same diameter protrusion coaxial with the surface of the outer peripheral portion as well as contact with the end face of the mounting opening on the back surface of the outer peripheral portion of the Kutsugaesen It is configured. Thus, when the cover plug is attached to the attachment port, the circular protrusion provided on the back surface of the outer peripheral portion comes into contact with the end surface of the attachment port portion, and the rear surface of the outer peripheral portion and the end surface of the attachment port portion are substantially the same. It comes into close contact with line contact. In this case, as compared with the case where the back surface of the outer peripheral portion and the end surface of the mounting opening portion are brought into close contact with each other, the pressure applied to the contact location is increased, and thus the sealing performance is improved.

そしてまた、必要に応じ、上記覆栓の外周部の周縁に沿って内向きの係合凹部を形成する一方、上記取付口部の端面の外側縁に沿って上記係合凹部が係合する外向きの係合凸部を形成した構成としている。これにより、例えば、工場で潤滑剤用カートリッジタンクに潤滑剤を封入する際、取付口部の端面に潤滑剤が付着することがあるが、例えば、覆栓を紙で形成して取付口部の開口を被覆する場合には、取付口部の端面に付着した潤滑剤により、密着性を損なって覆栓の保持が不十分になるが、本構成の覆栓では、覆栓の係合凹部を取付口部の係合凸部に係合するだけで覆栓を取付口部に取付けられるので、覆栓の保持を確実にすることができる。   Further, if necessary, an inward engagement recess is formed along the peripheral edge of the outer peripheral portion of the cover plug, while the engagement recess is engaged along the outer edge of the end surface of the mounting opening. The engaging projections in the direction are formed. Thus, for example, when the lubricant is sealed in the cartridge cartridge for lubricant at a factory, the lubricant may adhere to the end face of the attachment port portion. When covering the opening, the lubricant adhering to the end face of the mounting opening part impairs the adhesiveness and makes the covering plug insufficiently held. Since the cover plug can be attached to the attachment port portion simply by engaging with the engagement convex portion of the attachment port portion, the cover plug can be reliably held.

本発明の潤滑剤用カートリッジタンクによれば、この潤滑剤用カートリッジタンクを潤滑ポンプに取付ける際、取付口部の開口は覆栓によって被覆されているので、粘度の低いやわらかい潤滑剤を使用した場合でも、潤滑剤が取付口部から漏れることを防止できる。また、取付口部を潤滑ポンプの凹部に挿入すると、潤滑ポンプの給油口部によって覆栓の切断溝が切断されるので、給油口部が取付口部の開口に挿入され、容器本体内に封入されている潤滑剤が潤滑ポンプに供給されるようになる。即ち、容器本体内に封入されている潤滑剤は、取付口部を潤滑ポンプの凹部に取付けるまでの間は容器本体から漏れないが、潤滑剤用カートリッジタンクを潤滑ポンプに取付けた後は、容器本体から流出して潤滑ポンプに供給されるようになる。   According to the cartridge cartridge for lubricant of the present invention, when the cartridge cartridge for lubricant is attached to the lubrication pump, the opening of the attachment port is covered with the cover plug, so that a soft lubricant having a low viscosity is used. However, it is possible to prevent the lubricant from leaking from the mounting opening. Also, when the mounting port is inserted into the recess of the lubrication pump, the lubricating groove of the lubricating pump cuts the cutting groove of the cover plug, so that the oiling port is inserted into the opening of the mounting port and enclosed in the container body. The lubricated lubricant is supplied to the lubrication pump. That is, the lubricant sealed in the container body does not leak from the container body until the attachment port is attached to the recess of the lubrication pump, but after the lubricant cartridge tank is attached to the lubrication pump, the container It flows out of the main body and is supplied to the lubrication pump.

The cap 40 is formed with a thin cut groove 41 that is cut by the oil supply port 7 when the oil supply port 7 of the lubrication pump 1 is inserted into the opening 21 of the mounting port 20. The cutting groove 41 includes a circumferential groove 42 and a vertical groove 43.

円周溝４２は、図１乃至図６に示すように、潤滑ポンプ１の給油口部７の口径よりも大きな径の円形状に形成されている。
縦溝４３は、図１乃至図３，図５に示すように、円周溝４２の中心４４及び円周溝４２間に亘って複数形成されている。実施の形態では、十字状に４本形成されている。
この円周溝４２と縦溝４３とで囲繞される部分には、複数の片部４５が形成されている。実施の形態では４つ形成されている。 As shown in FIGS. 1 to 6, the circumferential groove 42 is formed in a circular shape having a diameter larger than the diameter of the oil supply port portion 7 of the lubrication pump 1.
As shown in FIGS. 1 to 3 and 5, a plurality of vertical grooves 43 are formed across the center 44 of the circumferential groove 42 and between the circumferential grooves 42. In the embodiment, four are formed in a cross shape.
A plurality of pieces 45 are formed in a portion surrounded by the circumferential groove 42 and the vertical groove 43. In the embodiment, four are formed.

また、図１乃至図９に示すように、円周溝４２の外側には、外周部４６が形成されている。この外周部４６の表面には、潤滑ポンプ１の凹部４の底面６に当接する円形の突条４７ａが設けられており、外周部４６の裏面には、取付口部２０の端面２４に当接するとともに外周部４６の表面の突条４７ａと同軸で同径の円形の突条４７ｂが設けられている。更に、外周部４６の周縁に沿って、取付口部２０に形成されている係合凸部２５が係合する内向きの係合凹部４８が形成されている。 Further, as shown in FIGS. 1 to 9, an outer peripheral portion 46 is formed outside the circumferential groove 42. A circular ridge 47 a that abuts against the bottom surface 6 of the recess 4 of the lubrication pump 1 is provided on the surface of the outer peripheral portion 46, and the rear surface of the outer peripheral portion 46 abuts against the end surface 24 of the mounting opening 20. In addition, a circular protrusion 47b having the same diameter and the same diameter as the protrusion 47a on the surface of the outer peripheral portion 46 is provided. Furthermore, an inward engagement recess 48 that engages with the engagement protrusion 25 formed in the mounting opening 20 is formed along the periphery of the outer peripheral portion 46.

更にまた、この覆栓４０には、切断溝４１が切断されたとき、複数の片部４５を夫々支持するヒンジ４９が設けられている。このヒンジ４９は、図２，図４乃至図６に示すように、片部４５と外周部４６との間に設けられており、このヒンジ４９を介して片部４５と外周部４６とを接続している。   Furthermore, the cover plug 40 is provided with hinges 49 that respectively support the plurality of pieces 45 when the cutting groove 41 is cut. As shown in FIGS. 2, 4 to 6, the hinge 49 is provided between the piece 45 and the outer peripheral portion 46, and the piece 45 and the outer peripheral portion 46 are connected via the hinge 49. doing.

このように構成される実施の形態に係る潤滑剤用カートリッジタンクＴに潤滑剤を封入するときは、以下のようにする。取付口部２０の上部から開口２１を通過させて潤滑剤を注入する。一定量注入したら、取付口部２０に形成されている係合凸部２５に覆栓４０の係合凹部４８を係合させて、取付口部２０の開口２１を覆栓４０で被覆する。このとき、注入する際に潤滑剤が取付口部２０の上部に形成されている端面２４に付着することがある。この場合、例えば、覆栓４０を紙で形成して取付口部２０の開口２１を被覆する場合には、取付口部２０の端面２４に付着した潤滑剤により、密着性を損なって保持が不十分になるが、本発明の覆栓４０では、覆栓４０の係合凹部４８を取付口部２０の係合凸部２５に係合するだけで覆栓４０を取付口部２０に取付けられるので、覆栓４０の保持を確実にすることができる。また、覆栓４０の外周部４６の裏面には円形の突条４７ｂが設けられており、覆栓４０を取付口部２０に取付ける際、この突条４７ｂが取付口部２０の端面２４と当接し、外周部４６の裏面と取付口部２０の端面２４とは略線接触で密着するようになる。この場合、外周部４６の裏面と取付口部２０の端面２４とを面接触で密着させた場合と比較して、接触場所に掛かる圧力が大きくなり、そのため、シール性が良くなる。そして、覆栓４０を取付けた取付口部２０にキャップ２２を被せる。このように潤滑剤が封入された容器本体１０を製品とし、箱詰する等して販売の用に供する。   When the lubricant is sealed in the lubricant cartridge tank T according to the embodiment configured as described above, the following is performed. Lubricant is injected through the opening 21 from the upper part of the mounting opening 20. After a certain amount of injection, the engagement concave portion 48 of the cover plug 40 is engaged with the engagement convex portion 25 formed in the attachment port portion 20, and the opening 21 of the attachment port portion 20 is covered with the cover plug 40. At this time, the lubricant may adhere to the end surface 24 formed on the upper portion of the attachment port portion 20 during injection. In this case, for example, when the cover plug 40 is formed of paper to cover the opening 21 of the mounting opening 20, the lubricant attached to the end surface 24 of the mounting opening 20 impairs adhesion and is not retained. Although it is sufficient, in the cover plug 40 of the present invention, the cover plug 40 can be attached to the attachment port portion 20 simply by engaging the engagement recess 48 of the cover plug 40 with the engagement convex portion 25 of the attachment port portion 20. Therefore, it is possible to reliably hold the cover plug 40. In addition, a circular protrusion 47 b is provided on the back surface of the outer peripheral portion 46 of the cover plug 40, and when the cover plug 40 is attached to the attachment opening 20, the protrusion 47 b contacts the end surface 24 of the attachment opening 20. The back surface of the outer peripheral portion 46 and the end surface 24 of the attachment port portion 20 come into close contact with each other by substantially line contact. In this case, compared with the case where the back surface of the outer peripheral part 46 and the end surface 24 of the attachment port part 20 are contact | adhered by surface contact, the pressure concerning a contact location becomes large, Therefore, sealing performance improves. Then, the cap 22 is put on the attachment opening 20 to which the cover plug 40 is attached. The container body 10 thus encapsulated with the lubricant is used as a product, which is then packed for use for sale.

この潤滑剤用カートリッジタンクＴを、潤滑ポンプ１に取付けるときは、以下のようにする。先ず、潤滑ポンプ１からカバー９を取外す。また、取付口部２０に被せられているキャップ２２を取外す。この状態で、容器本体１０を逆さにして取付口部２０を下側にする。このとき、取付口部２０の開口２１は覆栓４０によって被覆されており、この覆栓４０が潤滑剤を受け止めるので、粘度の低いやわらかい潤滑剤を使用した場合でも、潤滑剤が取付口部２０から漏れることを防止できる。   When this cartridge tank T for lubricant is attached to the lubrication pump 1, it is as follows. First, the cover 9 is removed from the lubrication pump 1. Further, the cap 22 that covers the mounting opening 20 is removed. In this state, the container body 10 is turned upside down so that the mounting opening 20 is on the lower side. At this time, the opening 21 of the attachment port portion 20 is covered with the cover plug 40, and the cover plug 40 receives the lubricant. Therefore, even when a soft lubricant having a low viscosity is used, the lubricant is attached to the attachment port portion 20. Can be prevented from leaking.

そして、潤滑剤用カートリッジタンクＴの取付口部２０を凹部４に挿入して、容器本体１０を回して取付口部２０の雄ネジ２３を潤滑ポンプ１の凹部４の雌ネジ４ａに螺合する。それから、潤滑ポンプ１にカバー９を取付ける。   Then, the mounting port 20 of the lubricant cartridge tank T is inserted into the recess 4, and the container body 10 is rotated to screw the male screw 23 of the mounting port 20 into the female screw 4 a of the recess 4 of the lubrication pump 1. . Then, the cover 9 is attached to the lubrication pump 1.

詳しくは、カートリッジタンクＴの取付けの際は、覆栓４０の中心と、取付口部２０の軸心は同一線上に設けられているので、給油口部２０の軸心も同一線上に位置させられる。取付口部２０を潤滑ポンプ１の凹部４に挿入しようとすると、凹部４の底面６に突出された給油口部７が覆栓４０の表面と接触する。そのまま挿入すると、給油口部７によって覆栓４０の中心から縦溝４３が切断され、４つの片部４５が給油口部７によって覆栓４０の中心を頂点として持ち上げられるようになる。これにより、円周溝４２が切断され、片部４５が容器本体１０内に入り込むようになる。切断溝４１が切断されると、給油口部７が取付口部２０の開口２１に挿入される。そして、取付口部２０の雄ネジ２３を潤滑ポンプ１の凹部４の雌ネジ４ａにねじ込んでいく。   Specifically, when the cartridge tank T is mounted, the center of the cover cap 40 and the axis of the mounting port 20 are provided on the same line, so that the axis of the oil supply port 20 is also positioned on the same line. . When the attachment port 20 is to be inserted into the recess 4 of the lubrication pump 1, the oil supply port 7 protruding from the bottom surface 6 of the recess 4 comes into contact with the surface of the cover plug 40. When inserted as it is, the longitudinal groove 43 is cut from the center of the cover plug 40 by the fuel filler opening 7, and the four pieces 45 are lifted by the fuel filler opening 7 with the center of the cover stopper 40 as a vertex. As a result, the circumferential groove 42 is cut, and the piece 45 enters the container body 10. When the cutting groove 41 is cut, the oil filler port 7 is inserted into the opening 21 of the mounting port 20. Then, the male screw 23 of the mounting opening 20 is screwed into the female screw 4 a of the recess 4 of the lubrication pump 1.

また、このとき、片部４５はヒンジ４９によって支持されているので、片部４５はヒンジ４９を介して外周部４６に接続され、片部４５が覆栓４０から離脱させられて容器本体１０内の潤滑剤を遊動することを防止することができる。これにより、片部４５が潤滑剤を遊動して給油口部７の注入口５を塞ぐことを防止でき、そのため、確実に潤滑剤を潤滑ポンプ１に供給できるようになる。   At this time, since the piece 45 is supported by the hinge 49, the piece 45 is connected to the outer peripheral portion 46 via the hinge 49, and the piece 45 is detached from the cover plug 40 to be inside the container body 10. It is possible to prevent loosening of the lubricant. Accordingly, it is possible to prevent the piece portion 45 from floating the lubricant and plugging the injection port 5 of the oil supply port portion 7, so that the lubricant can be reliably supplied to the lubrication pump 1.

取付口部２０の雄ネジ２３を潤滑ポンプ１の凹部４の雌ネジ４ａにねじ込んでいくと、覆栓４０の外周部４６の表面に設けられた円形の突条４７ａが、凹部４の底面６に当接するようになる。このとき、この突条４７ａによって、外周部４６の表面と凹部４の底面６とは略線接触で密着するようになる。この場合、外周部４６の表面と凹部４の底面６とを面接触で密着させた場合と比較して、接触場所に掛かる圧力が大きくなり、そのため、シール性が良くなる。   When the male screw 23 of the mounting opening 20 is screwed into the female screw 4 a of the recess 4 of the lubrication pump 1, the circular protrusion 47 a provided on the surface of the outer peripheral portion 46 of the cover plug 40 becomes the bottom surface 6 of the recess 4. Will come into contact. At this time, the surface of the outer peripheral portion 46 and the bottom surface 6 of the concave portion 4 come into close contact with each other by the linear protrusion 47a. In this case, compared with the case where the surface of the outer peripheral part 46 and the bottom face 6 of the recessed part 4 are contact | adhered by surface contact, the pressure concerning a contact location becomes large, Therefore, sealing performance improves.

この状態では、給油口部７の注入口５と容器本体１０内とが連通されるようになり、容器本体１０内に封入されている潤滑剤が給油口部７の注入口５を通過して流出し潤滑ポンプ１に供給されるようになる。即ち、容器本体１０内に封入されている潤滑剤は、キャップ２２を取外してから容器本体１０を逆さにして取付口部２０の雄ネジ２３を潤滑ポンプ１の凹部４の雌ネジ４ａに螺合して取付けるまでの間は容器本体１０から漏れないが、潤滑剤用カートリッジタンクＴを潤滑ポンプ１に取付けた後は、容器本体１０から流出して潤滑ポンプ１に供給されるようになる。   In this state, the inlet 5 of the filler port 7 and the inside of the container body 10 are communicated, and the lubricant sealed in the container body 10 passes through the inlet 5 of the filler port 7. It flows out and is supplied to the lubrication pump 1. That is, the lubricant sealed in the container main body 10 is screwed with the male screw 23 of the mounting opening 20 to the female screw 4 a of the concave portion 4 of the lubrication pump 1 by inverting the container main body 10 after removing the cap 22. However, after the lubricant cartridge tank T is attached to the lubrication pump 1, it flows out of the container body 10 and is supplied to the lubrication pump 1.

このように潤滑剤用カートリッジタンクＴが装着された潤滑ポンプ１を作動させるときは、以下のようにする。潤滑ポンプ１のポンプ部３を駆動して給油口部７から給油された潤滑剤を吐出する。潤滑ポンプ１を作動させると、潤滑剤用カートリッジタンクＴの容器本体１０から潤滑剤が消費されていく。   Thus, when operating the lubrication pump 1 with which the cartridge cartridge T for lubricants was mounted, it carries out as follows. The pump part 3 of the lubrication pump 1 is driven to discharge the lubricant supplied from the oil supply port part 7. When the lubrication pump 1 is operated, the lubricant is consumed from the container body 10 of the lubricant cartridge tank T.

潤滑剤用カートリッジタンクＴの潤滑剤が無くなったならば、新たな潤滑剤用カートリッジタンクＴと交換する。この際には、先ず、容器本体１０を回して、取付口部２０を潤滑ポンプ１の凹部４から取外す。このとき、覆栓４０の片部４５はヒンジ４９を介して外周部４６に接続されているので、片部４５が離脱することを防止することができる。   When the lubricant in the lubricant cartridge tank T runs out, it is replaced with a new lubricant cartridge tank T. At this time, first, the container main body 10 is rotated to remove the attachment port portion 20 from the recess 4 of the lubrication pump 1. At this time, since the piece 45 of the cover plug 40 is connected to the outer peripheral portion 46 via the hinge 49, it is possible to prevent the piece 45 from being detached.

使用後の潤滑剤用カートリッジタンクＴを潤滑ポンプ１から取外したならば、新たな潤滑剤用カートリッジタンクＴを上記と同様に潤滑ポンプ１に取付ければ良い。   If the used lubricant cartridge tank T is removed from the lubrication pump 1, a new lubricant cartridge tank T may be attached to the lubrication pump 1 in the same manner as described above.
